Hi, seems to be the year everything wears out on my pool. Salt generator, holes in lining, now heater. I have a Raypak 2100 heater that is probably 10 plus years old (been in our house 8 years). It started having a pilot light issue and after investigating I see water dripping down to the bottom of the heater case. There’s a lot of rust which I’m assuming is the heat exchanger rusting. This water is leaking on the pilot light so I manually light it and it eventually dries out the coils to light the heater. I can smell a lot of dampness when it starts and then it eventually burns off. Is my assumption correct that it’s the heat exchanger needing replaced?
